Theory for aerosol droplets from contaminated bubbles may shed light on spread of pollution, microplastics, and more

Bubbles burst when their caps rupture. Children discover this phenomenon every summer day, but it also underpins key mechanisms for the spread of pollutants, contaminants, and even infectious disease through the generation ...
